Alphafly 3

From Nike

The lightest Alphafly ever, and a world record smashing shoe before it is even launched, with the fastest ever men’s marathon, and the second fastest women’s marathon time already to its name, the Nike Women’s Air Zoom Alphafly Next Percent 3 in Sail/Black/Crimson Tint/Guava Ice is more than capable of living up to the hype.The distinctive shape may have disappeared, but the performance and marathon winning pedigree is still there, with the Nike Women’s Air Zoom Alphafly Next Percent 3 taking the formula for success to new heights. The full-length carbon plate is wider for a more stable platform to explode from, and that ZoomX foam midsole is now fully connected, giving even smoother transitions, and taking away any reason heel strikers may have had to skip the shoe in the past. It also has a new upper, Atomknit is designed to give improved containment, in every direction, while simultaneously improving breathability. The integrated tongue uses lofted padding to alleviate lace pressure. If you haven’t tried the Alphafly before, now is a great time to try it, smoother, lighter, and blisteringly fast, and if you are already a convert? It just got even better, with all the propulsion you know and love driving you to new heights.
